Helmholtz-Resonatoren für Doppelglasfenster

(PresseBox) (Darmstadt, )
Mit zunehmendem Verkehrsaufkommen steigt auch der Lärmpegel in unseren Städten. Die Adaptronik bietet interessante Ansatzpunkte, um den Krach von Wohnungen und Büros fernzuhalten. Zur Reduktion schmalbandiger Lärmquellen bieten sich adaptive Helmholtz-Resonatoren an. Wissenschaftler des Fraunhofer-Instituts für Betriebsfestigkeit und Systemzuverlässigkeit LBF zeigen die innovative Technik bei der diesjährigen Hannover-Messe vom 7. bis 11. April auf dem Fraunhofer-Adaptronikstand in Halle 2, Stand D13.

Helmholtz-Resonatoren sind passive Maßnahmen zur Reduktion von Schallfeldern in Räumen und durch Doppelglasfenster. Der Vorteil liegt auf der Hand: Passive Systeme verbrauchen wesentlich weniger Energie als aktive Maßnahmen. Die meisten Störquellen weisen eine zeitveränderliche Frequenzcharakteristik auf.
